, 2019 Phospholipase C (PLC) family members constitute a family of diverse enzymes. Thirteen different family members have been cloned. These family members have unique structures that mediate various functions. Although PLC family members all appear to signal through the bi-products of cleaving phospholipids, it is clear that each family member, and at times

Journal of Lipid Research, 2001 Familial HDL deficiency (FHD) is the heterozygous form of Tangier disease (TD). Mutations of the ABCA1 gene cause FHD and TD. FHD/TD cells are unable to normally efflux cholesterol onto nascent HDL particles, which are rapidly catabolized. TD fibroblasts

Lipid levels in sperm, eggs, and during fertilization in Xenopus laevis
Journal of Lipid Research, 2008 Critical developmental periods, such as fertilization, involve metabolic activation, membrane fusion events such as sperm-egg or plasma membrane-cortical granule merger, and production and hydrolysis of phospholipids.

Secretory Phospholipases A2 in Plants [PDF]
, 2019 Secreted phospholipases (sPLA2s) in plants are a growing group of enzymes that catalyze the hydrolysis of sn-2 glycerophospholipids to lysophospholipids and free fatty acids. Until today, around only 20 sPLA2s were reported from plants.

Activation of phospholipase D-2 by P2X7 agonists in rat submandibular gland acini
Journal of Lipid Research, 2002 Exogenous ATP stimulated phospholipase D (PLD), but not sphingomyelinase in rat submandibular gland (SMG) acini. PLD activation was dependent upon extracellular Ca2+ and did not involve intracellular Ca2+ mobilization or phosphoinositide-specific ...
